new investments

In the Information Memorandum it states:

"Since the balance date of the unaudited Statement of Financial Position, the Company has made further investments in ASX listed companies, which as at the date of this Information Memorandum has a total market value of approximately $5,000,000. This includes investments in a junior gold exploration company, a uranium exploration company, a copper-gold explorer and a junior oil and gas exploration company (all of which are not related parties of the Company or any of the Directors)."

Why are these not announced to the market?

(Or am I missing something)
